+      The GNU General Public License (GPL)
+      Version 2, June 1991
+
+      Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+      59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
+      Everyone is permitted to copy and distribute verbatim copies
+      of this license document, but changing it is not allowed.
+
+      Preamble
+
+      The licenses for most software are designed to take away your freedom to 
+      share and change it. By contrast, the GNU General Public License is 
+      intended to guarantee your freedom to share and change free software--to 
+      make sure the software is free for all its users. This General Public 
+      License applies to most of the Free Software Foundation's software and to 
+      any other program whose authors commit to using it. (Some other Free 
+      Software Foundation software is covered by the GNU Library General Public 
+      License instead.) You can apply it to your programs, too.
+
+      When we speak of free software, we are referring to freedom, not price. 
+      Our General Public Licenses are designed to make sure that you have the 
+      freedom to distribute copies of free software (and charge for this service 
+      if you wish), that you receive source code or can get it if you want it, 
+      that you can change the software or use pieces of it in new free programs; 
+      and that you know you can do these things.
+
+      To protect your rights, we need to make restrictions that forbid anyone to 
+      deny you these rights or to ask you to surrender the rights. These 
+      restrictions translate to certain responsibilities for you if you 
+      distribute copies of the software, or if you modify it.
+
+      For example, if you distribute copies of such a program, whether gratis or 
+      for a fee, you must give the recipients all the rights that you have. You 
+      must make sure that they, too, receive or can get the source code. And you 
+      must show them these terms so they know their rights.
+
+      We protect your rights with two steps: (1) copyright the software, and (2) 
+      offer you this license which gives you legal permission to copy, 
+      distribute and/or modify the software.
+
+      Also, for each author's protection and ours, we want to make certain that 
+      everyone understands that there is no warranty for this free software. If 
+      the software is modified by someone else and passed on, we want its 
+      recipients to know that what they have is not the original, so that any 
+      problems introduced by others will not reflect on the original authors' 
+      reputations.
+
+      Finally, any free program is threatened constantly by software patents. We 
+      wish to avoid the danger that redistributors of a free program will 
+      individually obtain patent licenses, in effect making the program 
+      proprietary. To prevent this, we have made it clear that any patent must 
+      be licensed for everyone's free use or not licensed at all.
+
+      The precise terms and conditions for copying, distribution and 
+      modification follow.
+
+      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+      0. This License applies to any program or other work which contains a 
+      notice placed by the copyright holder saying it may be distributed under 
+      the terms of this General Public License. The "Program", below, refers to 
+      any such program or work, and a "work based on the Program" means either 
+      the Program or any derivative work under copyright law: that is to say, a 
+      work containing the Program or a portion of it, either verbatim or with 
+      modifications and/or translated into another language. (Hereinafter, 
+      translation is included without limitation in the term "modification".) 
+      Each licensee is addressed as "you".
+
+      Activities other than copying, distribution and modification are not 
+      covered by this License; they are outside its scope. The act of running 
+      the Program is not restricted, and the output from the Program is covered 
+      only if its contents constitute a work based on the Program (independent 
+      of having been made by running the Program). Whether that is true depends 
+      on what the Program does.
+
+      1. You may copy and distribute verbatim copies of the Program's source 
+      code as you receive it, in any medium, provided that you conspicuously and 
+      appropriately publish on each copy an appropriate copyright notice and 
+      disclaimer of warranty; keep intact all the notices that refer to this 
+      License and to the absence of any warranty; and give any other recipients 
+      of the Program a copy of this License along with the Program.
+
+      You may charge a fee for the physical act of transferring a copy, and you 
+      may at your option offer warranty protection in exchange for a fee.
+
+      2. You may modify your copy or copies of the Program or any portion of it, 
+      thus forming a work based on the Program, and copy and distribute such 
+      modifications or work under the terms of Section 1 above, provided that 
+      you also meet all of these conditions:
+
+        a) You must cause the modified files to carry prominent notices stating 
+        that you changed the files and the date of any change.
+
+        b) You must cause any work that you distribute or publish, that in whole 
+        or in part contains or is derived from the Program or any part thereof, 
+        to be licensed as a whole at no charge to all third parties under the 
+        terms of this License.
+
+        c) If the modified program normally reads commands interactively when 
+        run, you must cause it, when started running for such interactive use in 
+        the most ordinary way, to print or display an announcement including an 
+        appropriate copyright notice and a notice that there is no warranty (or 
+        else, saying that you provide a warranty) and that users may 
+        redistribute the program under these conditions, and telling the user 
+        how to view a copy of this License. (Exception: if the Program itself is 
+        interactive but does not normally print such an announcement, your work 
+        based on the Program is not required to print an announcement.)
+
+      These requirements apply to the modified work as a whole. If identifiable 
+      sections of that work are not derived from the Program, and can be 
+      reasonably considered independent and separate works in themselves, then 
+      this License, and its terms, do not apply to those sections when you 
+      distribute them as separate works. But when you distribute the same 
+      sections as part of a whole which is a work based on the Program, the 
+      distribution of the whole must be on the terms of this License, whose 
+      permissions for other licensees extend to the entire whole, and thus to 
+      each and every part regardless of who wrote it.
+
+      Thus, it is not the intent of this section to claim rights or contest your 
+      rights to work written entirely by you; rather, the intent is to exercise 
+      the right to control the distribution of derivative or collective works 
+      based on the Program.
+
+      In addition, mere aggregation of another work not based on the Program 
+      with the Program (or with a work based on the Program) on a volume of a 
+      storage or distribution medium does not bring the other work under the 
+      scope of this License.
+
+      3. You may copy and distribute the Program (or a work based on it, under 
+      Section 2) in object code or executable form under the terms of Sections 1 
+      and 2 above provided that you also do one of the following:
+
+        a) Accompany it with the complete corresponding machine-readable source 
+        code, which must be distributed under the terms of Sections 1 and 2 
+        above on a medium customarily used for software interchange; or,
+
+        b) Accompany it with a written offer, valid for at least three years, to 
+        give any third party, for a charge no more than your cost of physically 
+        performing source distribution, a complete machine-readable copy of the 
+        corresponding source code, to be distributed under the terms of Sections 
+        1 and 2 above on a medium customarily used for software interchange; or,
+
+        c) Accompany it with the information you received as to the offer to 
+        distribute corresponding source code. (This alternative is allowed only 
+        for noncommercial distribution and only if you received the program in 
+        object code or executable form with such an offer, in accord with 
+        Subsection b above.)
+
+      The source code for a work means the preferred form of the work for making 
+      modifications to it. For an executable work, complete source code means 
+      all the source code for all modules it contains, plus any associated 
+      interface definition files, plus the scripts used to control compilation 
+      and installation of the executable. However, as a special exception, the 
+      source code distributed need not include anything that is normally 
+      distributed (in either source or binary form) with the major components 
+      (compiler, kernel, and so on) of the operating system on which the 
+      executable runs, unless that component itself accompanies the executable.
+
+      If distribution of executable or object code is made by offering access to 
+      copy from a designated place, then offering equivalent access to copy the 
+      source code from the same place counts as distribution of the source code, 
+      even though third parties are not compelled to copy the source along with 
+      the object code.
+
+      4. You may not copy, modify, sublicense, or distribute the Program except 
+      as expressly provided under this License. Any attempt otherwise to copy, 
+      modify, sublicense or distribute the Program is void, and will 
+      automatically terminate your rights under this License. However, parties 
+      who have received copies, or rights, from you under this License will not 
+      have their licenses terminated so long as such parties remain in full 
+      compliance.
+
+      5. You are not required to accept this License, since you have not signed 
+      it. However, nothing else grants you permission to modify or distribute 
+      the Program or its derivative works. These actions are prohibited by law 
+      if you do not accept this License. Therefore, by modifying or distributing 
+      the Program (or any work based on the Program), you indicate your 
+      acceptance of this License to do so, and all its terms and conditions for 
+      copying, distributing or modifying the Program or works based on it.
+
+      6. Each time you redistribute the Program (or any work based on the 
+      Program), the recipient automatically receives a license from the original 
+      licensor to copy, distribute or modify the Program subject to these terms 
+      and conditions. You may not impose any further restrictions on the 
+      recipients' exercise of the rights granted herein. You are not responsible 
+      for enforcing compliance by third parties to this License.
+
+      7. If, as a consequence of a court judgment or allegation of patent 
+      infringement or for any other reason (not limited to patent issues), 
+      conditions are imposed on you (whether by court order, agreement or 
+      otherwise) that contradict the conditions of this License, they do not 
+      excuse you from the conditions of this License. If you cannot distribute 
+      so as to satisfy simultaneously your obligations under this License and 
+      any other pertinent obligations, then as a consequence you may not 
+      distribute the Program at all. For example, if a patent license would not 
+      permit royalty-free redistribution of the Program by all those who receive 
+      copies directly or indirectly through you, then the only way you could 
+      satisfy both it and this License would be to refrain entirely from 
+      distribution of the Program.
+
+      If any portion of this section is held invalid or unenforceable under any 
+      particular circumstance, the balance of the section is intended to apply 
+      and the section as a whole is intended to apply in other circumstances.
+
+      It is not the purpose of this section to induce you to infringe any 
+      patents or other property right claims or to contest validity of any such 
+      claims; this section has the sole purpose of protecting the integrity of 
+      the free software distribution system, which is implemented by public 
+      license practices. Many people have made generous contributions to the 
+      wide range of software distributed through that system in reliance on 
+      consistent application of that system; it is up to the author/donor to 
+      decide if he or she is willing to distribute software through any other 
+      system and a licensee cannot impose that choice.
+
+      This section is intended to make thoroughly clear what is believed to be a 
+      consequence of the rest of this License.
+
+      8. If the distribution and/or use of the Program is restricted in certain 
+      countries either by patents or by copyrighted interfaces, the original 
+      copyright holder who places the Program under this License may add an 
+      explicit geographical distribution limitation excluding those countries, 
+      so that distribution is permitted only in or among countries not thus 
+      excluded. In such case, this License incorporates the limitation as if 
+      written in the body of this License.
+
+      9. The Free Software Foundation may publish revised and/or new versions of 
+      the General Public License from time to time. Such new versions will be 
+      similar in spirit to the present version, but may differ in detail to 
+      address new problems or concerns.
+
+      Each version is given a distinguishing version number. If the Program 
+      specifies a version number of this License which applies to it and "any 
+      later version", you have the option of following the terms and conditions 
+      either of that version or of any later version published by the Free 
+      Software Foundation. If the Program does not specify a version number of 
+      this License, you may choose any version ever published by the Free 
+      Software Foundation.
+
+      10. If you wish to incorporate parts of the Program into other free 
+      programs whose distribution conditions are different, write to the author 
+      to ask for permission. For software which is copyrighted by the Free 
+      Software Foundation, write to the Free Software Foundation; we sometimes 
+      make exceptions for this. Our decision will be guided by the two goals of 
+      preserving the free status of all derivatives of our free software and of 
+      promoting the sharing and reuse of software generally.
+
+      NO WARRANTY
+
+      11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 
+      FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 
+      OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 
+      PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 
+      OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 
+      MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 
+      TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 
+      PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 
+      REPAIR OR CORRECTION.
+
+      12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
+      WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
+      REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 
+      INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES 
+      ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT 
+      LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES 
+      SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE 
+      WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN 
+      ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+      END OF TERMS AND CONDITIONS
